CORTLAND, N.Y. -- A district attorney in upstate New York admits that he acted in pornographic movies in the 1970s.

Mark Suben, the DA in Cortland County near Syracuse since 2008, held a news conference Friday to say he had lied about his past in the days before this year's election.

He is apologizing for his actions and says he used "bad judgment" by acting in porn and by recently denying it. He wouldn't take questions, including whether he should resign.

WSTM-TV in Syracuse published a story Friday that said Suben had acted under his name and the pseudonym Gus Thomas. That news story followed a posting on YouTube that compared images of Suben with Thomas.

Suben previously acknowledged he was an actor in New York City in the 1970s but denied acting in adult films.
